C Correct answer
Explanation

InStrRev searches backwards through the string and returns the START position of the last occurrence. The string 'abc abc' contains 'abc' at positions 1 and 5 (with a space at position 4). Searching from the right finds 'abc' starting at position 5, not 2 or 3. Option D (0) would mean not found, which is incorrect.
